CONDUl'l FOR ELECTRIC WIRES.

sPEcIFlcATIoN forming part of Letters Patent No. 686,419, dated November 12, 1901.

Application filed April 2, 1901.

To all whom t may concern:

Be itknown that I, EMMETT D. PAGE, a citizen of the United States, residing in New York city, borough of Brooklyn, State of New York, have invented certain new and useful Improvements in Conduits for Electric Wires, of which the following is a specication.

VMyv invention relates to improvements in the class of conduits shown in United States Letf" ters Patent No. 667,567, issued to ine on February 5, 1901, for improvements in conduits,

&c.; and the object of my present inventionbroken, of a conduit embodying my inven-v tion; and Fig. 2 is a cross-section thereof.

In the drawings the letter A indicates the conduit proper, which is shown substantially in trough form, having a bottom a and side Walls a2, and B is the cover. The conduit is preferably made of sheet metal bent to the desired shape, and theouter edges of the side walls are provided with opposed longitudinally-extending grooves c, adapted to receive the corresponding edges of the cover B. The grooves c are preferably formed by bending the metal of the sides a2 into suitable shape, as shown, so that the outer webs or edges will overlie the edges of the cover and the cover Will lie upon the underlying laterally-extending portions of the grooves. The cover B is made of relatively thin metal and is corrugated or grooved transversely at b, the depth of the grooves c being such as to receive such grooved or corrugated portion of the cover, as shown in Fig. 2. By having the cover B corrugated it can be bent outwardly or in a direction substantially perpendicular to its Serial No. 54,021. iNo model.)

length, so as to be readily withdrawn from the grooves in the conduit or can be straightened out as it is pushed into said grooves, while at the same tiinethe transverse corrugations tend to stiften the cover, so that it will resist pressure and blows. By preference the outer webs ot' the'grooves c will be made pliable, whereby they can be bent outwardly to enable a portion of the cover to be inserted at or removed from any desired part of the conduit, and as the cover can be readily bent it will be apparent that it can be connected with or disconnected from the grooves at such points by sliding it into and from the grooves. The grooves of the conduit hold the cover rmly upon the same and all the advantages in the form of conduit shown in my said patent are present in this invention, with the additional advantage of the cover being strengthened, while Vat the same time being permitted to be readily bent when being applied or detached. The v vconduit and the cover when made of metal can be used as a grounded circuit, and one or more electric wires can be placed in the conduit, according to dimensions. In Fig. 2 I have shown one insulated wire in the conduit. It is also evident that more than one channel or duct can be made in the conduit, as illustrated in my said patent.

The conduit can be applied to a support by nailing or screwing it thereto, and after the wires are laid in the same the cover can be applied. Any part of the wires in the conduit can be reached readily by bending outwardly the Webs of grooves and cutting the adjacent part of the cover transversely and then pulling the saine outwardly from the permit the cover to be bent laterally, and means for holding the cover upon the conduit, substantially as described.

2. Aconduit adapted to receive one 0r more wires or the like and provided with a cover having transverse grooves or corrugations adapted to permit the cover to be bent laterally, said conduit having longitudinally-extending opposed grooves to receive the edges of the cover, whereby the latter may be slid 1o along the conduit, substantially as described.
